Abstract: 1514350 Correcting speed and length measurements H ALMGREN and L MILLGARD 17 Dec 1976 [18 Dec 1975] 52929/76 Heading G1N The invention relates to a method of automatically correcting a measuring instrument which measures the velocity and length of an object 17. The method comprises multiplying in a multiplier 5 the output signal of the measuring instrument 1, the signal being proportioned to the velocity of the object 7, by a scale or correction factor, the factor being a quotient formed by the distance L between two pick-ups 2, 3 created along the path of movement of the object divided by the number which is obtained when the output signal of the measuring instrument is integrated as in integrator 4 over the time interval during which a predetermined portion or creation of the object passes through the distance between the pick-ups 2, 3. If a plurality of objects are to be measured the factor is redetermined or recalculated for each object. Alternatively if an "endless" object is being measured the factor is redetermined at predetermined intervals of time. The pick-ups may comprise photo-cells and a further pick-up 6 may be provided upstream of the measuring instrument 1 for measuring object of "finite" length.

Filed: 1972-11-15
Abstract: 1346109 Watches A SCHILD S A 15 Nov 1971 [26 Nov 1970] 52958/71 Heading G3T An arrangement for releasably fastening a dial (17), Fig. 4 (not shown) to a watch pillar plate 1 comprises two spring members 4 each of which may be flexed to the position shown in Fig. 2 wherein a bevel edge 16 on the member is clear of a hole 3 in the pillar plate so that a foot 15 of the dial may be positioned in the hole. The member is retained in the flexed position by engagement of head 8 in a notch 11 in the side wall of a recess 2 in the pillar plate. Upon its release, the member tries to take up the position of Fig. 1 so that the bevel 16 cuts into the side of the foot 15 to retain the dial. This release is produced by inserting a pointed tool in a further hole 12 in the pillar plate, to engage a protrusion 10 on the spring member. The latter may be restored to the flexed position, thus releasing the dial, by engaging a tool in notch 9 from the side of the movement. The member 4 is retained in the recess 2 by its foot 5 which is forcefitted in two notches.

Abstract: 1373119 Magnetic storage arrangements WESTERN ELECTRIC CO Inc 16 Nov 1971 [16 Nov 1970 12 April 1971 29 Oct 1971] 53125/71 Heading H3B [Also in Division B1] A garnet substrate on which a garnet layer is grown by liquid phase epitaxial deposition (see Division B1) is used in magnetic devices in particular in "bubble" devices for switching, memory and logic functions. Such devices are shown in Figs. 1 and 2. Fig. 1 shows an arrangement 10 including a sheet or slice 11 of material in which single wall domains can be moved by bar and T-shaped segments and the reorienting in-plane field rotates clockwise in the plane of sheet 11 as viewed. The reorienting field is represented by block 12 and may comprise mutually orthogonal coil pairs (not shown) driven in quadrature. Only closed "information" loops are shown. The movement of domain patterns simultaneously in all the registers represented by loops is synchronized by the in-plane field source 12. Each rotation of the inplane field advances a next consecutive bit to  location 13 in each register. The movement of bits in the vertical channel is synchronized with this movement. In normal operation the horizontal channels are occupied by domain patterns and the vertical channel is unoccupied. For read or write operations the domain pattern is transferred to the vertical loop and the locus of the transfer function is indicated by broken loop T encompassing the vertical channel. Transfer is under the control of a transfer circuit 14 which may include a shift register tracking circuit for controlling the transfer of a selected word from memory. A read or a write operation is responsive to signals under the control of control circuit 16. The termination of either a write or a read operation terminates in the transfer of a pattern of domains to the horizontal channel. Fig. 2 shows a portion of an overlay pattern defining a representative horizontal channel in which a domain is moved. The overlay pattern contains repetitive segments. When the field is initially in an orientation as indicated by arrow H, one cycle of the field comprises four phases which moves a domain consecutively to the positions designated by the encircled numerals 1, 2, 3 and 4. The domain patterns in the channels correspond to the repeat pattern of the overlay. Entire domain patterns representing consecutive binary words accordingly move consecutively to positions 13. A domain in position 4 is accordingly ready to begin its transfer cycle.
